Hi,
I once turn off all of the unnecessary options in .config and the
kernel can be compiled within three minutes. But I also remove
USB,Networking,video, and mouse drivers, so the newer kernel is very
tiny and it's useless except debugging.
Besides, I use bochs and gdb to debug kernel source and it's very
convenient. Recently, I find DDD is an awesome debugger, so I highly
recommend it.

Good Luck.
